The Appendix is intended to receive such unsubstantial variants as seemed unworthy of a place at the foot of the text—errors of the scribe, frequently recurring itacisms, rejected spellings of an ordinary type, minute discrepancies between the MSS. and the printed text.

I don't own a copy of this module... but my PDF of Swete's LXX indicates that this reference is actually taken from the appendix. In Swete's text of Genesis, the main apparatus moves from 48:1 to 48:3, and this reference is included in the appendix at the end of the volume.

So, it looks like the creators of the module incorporated the references from the appendix into the main apparatus, and added the notation "[appendix]" to indicate their origin.

You're welcome! As someone who values these "unsubstantial variants" and considers them to be extremely important in the understanding of the development of the biblical text, I think Accordance has performed a real service by making them more available to the reader (as with the electronic edition of NA28).
